Description

Technical Field

[0001] This utility model belongs to the field of diamond wire saw technology, specifically relating to a weighing and sorting device for a steel substrate used in diamond wire saws. Background Technology

[0002] Diamond wire saws are widely used as tools for cutting materials such as stone and concrete. They mainly consist of a steel wire rope and beads spaced along the wire rope. The beads are composed of a steel matrix and a diamond-containing multiphase material wrapped around the outer cylindrical surface of the steel matrix. The beads are a crucial component of the diamond wire saw, and their manufacturing quality is closely related to the overall quality of the saw.

[0003] Current manufacturing techniques for beads typically involve first automatically cold-pressing a diamond-mixed multiphase material with a steel bead matrix into a cold-pressed bead blank, then sintering the blank in a graphite mold. If the weight of the multiphase material is inconsistent, the height of the beads will also be inconsistent. Since each mold requires loading over 100 cold-pressed bead blanks simultaneously, heavier beads, due to their high multiphase material density, are prone to damage during sintering due to excessive pressure on the upper and lower pressing heads. Conversely, lighter beads, due to their low multiphase material density, suffer from poor performance. This problem is one of the main reasons for the short lifespan of the graphite molds used for sintering and the unstable quality of the beads. Current solutions mainly involve frequently adjusting the automatic cold-pressing and sintering process parameters and replacing the cold-pressing molds, resulting in low production efficiency and high costs. More seriously, the problems of low lifespan of sintered graphite molds and unstable bead quality have not been fundamentally solved. The lifespan of sintered graphite molds varies, and the stability of bead quality has not been significantly improved.

[0004] Therefore, controlling the weight of multiphase materials is crucial. However, during bead manufacturing, the steel matrix that makes up the beads cannot be separated from the multiphase material. The weight of the multiphase material cannot be weighed separately; it can only be estimated by weighing the beads. To ensure the accuracy of the estimated multiphase material weight, the weights of each steel matrix bead must be approximately the same. However, currently, maintaining a consistent steel matrix weight would significantly increase manufacturing costs. The best method to ensure similar steel matrix weights is to weigh each bead individually and use them in weight-based categories.

[0005] Based on the above shortcomings, this application proposes a weighing and sorting device for steel substrates used in diamond wire saws. By dividing the steel substrates into weight classes, it lays the foundation for further dividing the multiphase materials of beads into weight classes. During sintering, the multiphase materials of beads in the same or adjacent classes are placed in the same mold for sintering, fundamentally solving the industry problems of low lifespan of sintering graphite molds and unstable bead quality.

[0022] In addition, this utility model provides a weighing and classification method:

[0023] During sorting, the vibrating feeding tray guides the steel substrate into the feeding guide rail. The steel substrate falls onto the weighing tray through the feeding guide rail, where the electronic scale obtains the weight of the steel substrate. After weighing, a push-pull feeding electromagnet pushes the steel substrate onto the discharge conveyor belt. Based on the weighing weight and sorting criteria, the steel substrate is transferred to the target push-pull discharge electromagnet and the location of the material box. Under the push of the push-pull discharge electromagnet, the steel substrate is pushed into the material box, completing the sorting.

[0024] Specifically, let the number of electronic scales be n, the number of weight ranges on the steel base be m, the lightest weight range be W0, and the weight difference between each range be a. After obtaining the weighing weight, the values ​​are assigned according to the following table:

[0025]

[0027] The discharge conveyor belt moves forward and stops at K1L (where L represents the distance between adjacent push-pull discharge electromagnets). The I1th push-pull discharge electromagnet activates, pushing the steel substrate next to the I1th push-pull discharge electromagnet 7 into the corresponding material box; then it resets.

[0028] When K1=G1, the i-th digit I1=K1-n+1;

[0029] When K1=G2, the i-th digit I1=K1-n+2;

[0048] Compared with the prior art, this utility model has the following advantages:

[0049] This invention's weighing and sorting device enables high-speed weight-based sorting of small components such as beaded steel substrates, laying the foundation for further weight-based sorting of beaded multiphase materials.

Detailed Implementation

[0056] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0057] A weighing and sorting device for a steel substrate used in diamond wire saws, such as Figure 1 and Figure 2 As shown, it includes a feeding mechanism, a weighing mechanism, and a conveying and discharging mechanism.

[0058] The feeding mechanism includes a vibrating feeding plate 2 and a feeding guide rail 1;

[0059] The weighing mechanism includes a push-pull type electromagnet 5, an electronic scale 4, and a weighing pan 3. The weighing pan 3 is installed on the top of the electronic scale 4, and the push-pull type electromagnet 5 is installed on one side of the weighing pan 3.

[0060] The material conveying mechanism includes a material conveyor belt 6, a push-pull material conveyor 7, and a material box 8. The material conveyor belt 6 and the push-pull material guide electromagnet 5 are located on both sides of the weighing pan 3, and the push-pull material conveyor 7 and the material box 8 are located on both sides of the material conveyor belt 6.

[0061] From the above and combined Figure 1 and Figure 2 It can be known that:

[0062] The figure shows two vibrating feeding trays 2, four feeding guide rails 1, four weighing mechanisms, six push-pull discharge electromagnets 7, and six material boxes 8, which are used to classify steel substrates by weighing.

[0063] During sorting, the vibrating feeding plate 2 guides the steel substrate into the feeding guide rail 1. The steel substrate falls into the weighing plate 3 through the feeding guide rail 1. At this time, the electronic scale 4 obtains the weight of the steel substrate. After weighing, the push-pull feeding electromagnet 5 pushes the steel substrate onto the discharge conveyor belt 6. According to the weighing weight and sorting standards, the steel substrate is transferred to the target push-pull discharge electromagnet 7 and the material box 8. Under the push of the push-pull discharge electromagnet 7, the steel substrate is pushed into the material box 8, completing the sorting.

[0064] Specifically, regarding the specific material supply of the aforementioned feeding guide 1: as follows... Figure 3 and Figure 4As shown, the feeding guide rail 1 includes a horizontal section and an inclined section connected to the discharge end of the horizontal section. The horizontal section is provided with a liftable feeding top rod 101, and the inclined section is provided with a liftable feeding stop rod 102. In addition, push-pull feeding electromagnets 103 are fixed at the bottom of both the horizontal section and the inclined section of the feeding guide rail 1, and the feeding top rod 101 and the feeding stop rod 102 are respectively connected to two push-pull feeding electromagnets 103.

[0065] Specifically, regarding the weighing mechanism, to ensure stable delivery to the weighing pan 3, as follows: Figure 3 As shown: The weighing pan 3 has a positioning U-shaped bottom surface.

[0066] Specifically, the discharge conveyor belt 6 is equipped with at least one set of baffles 601. Each set of baffles 601 includes a left side plate and a right side plate, with a height difference of 5mm to 15mm between the left and right side plates, and a storage groove is formed between the left and right side plates. Regarding the operation of the discharge conveyor belt 6, a stepper motor a, a driving wheel b, and a driven wheel c are correspondingly provided. The discharge conveyor belt 6 is fitted over the driving wheel b and the driven wheel c, with the driving wheel b being driven to rotate by the stepper motor a. Additionally, a photoelectric switch d is installed on one side of the discharge conveyor belt 6. Specifically, the start and stop of the stepper motor a are controlled by the detection feedback of the baffles 501 via the photoelectric switch d.

[0067] In summary, the control method for the overall device is as follows:

[0068] (1) Initial position correction

[0069] The stepper motor a is started to drive the discharge conveyor belt 6 forward. When the center of the photoelectric switch d is aligned with the nearest left side plate (baffle plate 601), the photoelectric switch d feedback controls the stepper motor a to stop. At this time, the center line of the feeding guide rail 1 on each electronic scale 4 coincides with the center line of the corresponding set of baffle plates 601, and the center line of the push-pull discharge electromagnet 7 coincides with the center line of the corresponding set of baffle plates 601.

[0070] (2) Feeding

[0071] The vibrating feeding plate 2 is activated to transport the steel substrate onto the feeding guide rail 1; at this time, the feeding top rod 101 and the feeding stop rod 102, driven by the push-pull feeding electromagnet 103, move in the following manner: Figure 5 As shown in Figure D, in this state, the steel substrate is continuously fed until it fills the feeding guide 1 and forms a complete structure. Figure 5 As shown in Figure A. Specifically, at least the upper part of the feeding stop bar 102 is provided with a stopping step parallel to the horizontal section of the feeding guide rail 1, thereby combining... Figure 5 As can be seen from section A, the foremost steel base is supported by the horizontal section (feeding guide rail 1) and the feeding stop bar 102.

[0072] like Figure 5 As shown in B and C, two push-pull feeding electromagnets 103 are activated simultaneously. At this time, the feeding top rod 101 extends upward to the horizontal section of the feeding guide rail 1, and the material-stopping step of the feeding top rod 101 is flush with the horizontal section of the feeding guide rail 1. The feeding stop rod 102 descends into the inclined section of the feeding guide rail 1. At least at the top of the feeding top rod 101, there is a guiding inclined surface that is connected to the discharge end of the feeding guide rail 1, so that the foremost steel substrate slides down the inclined section and is discharged (the discharged steel substrate falls onto the weighing pan 3).

[0073] After exporting a steel substrate, as shown in Figures 5C and 5D, two push-pull feeding electromagnets 103 are simultaneously activated. At this time, the feeding top rod 101 retracts into the horizontal section, while the feeding stop rod 102 extends out of the inclined section. Under the feeding push of the vibrating feeding plate 2, the feeding is... Figure 5 The steel substrate in section B / C, which was blocked by the feed rod 101, continued to move forward and eventually recovered. Figure 5 State A.

[0074] (3) Weighing

[0075] like Figure 3 As shown, the steel substrate slides down the inclined section onto the weighing pan 3, and the weight of the steel substrate is obtained by the electronic scale 4.

[0076] Let the number of electronic scales 4 be n, the number of weight ranges of the steel base be m, the lightest weight range be W0, the weight difference between each range be a, and the electronic scales 4 be classified and assigned values ​​as shown in Table 1 below based on their weighing weight.

[0077]

[0078] Based on the above, assuming n = 4, m = 6, W0 = 1.5g, a = 0.02g, we obtain the following Table 2:

[0079] Table 2

[0080]

[0081] After weighing, the steel substrate is pushed into the storage trough on the discharge conveyor belt 6 by the push-pull type guide electromagnet 5.

[0082] (4) Sorted discharge

[0083] Start the stepper motor 4 to drive the discharge conveyor belt 6 to discharge the material.

[0084] Assign values ​​G1, G2, G3...G to the n weight data obtained from n electronic scales. n Sort the data in ascending order, with the sorting order set as K1, K2, K3, ..., K.n .

[0085] The discharge conveyor belt 6 moves forward and stops at K1L (where L represents the distance between adjacent push-pull discharge electromagnets 7). The I1th push-pull discharge electromagnet 7 is activated, pushing the steel substrate next to the I1th push-pull discharge electromagnet 7 into the corresponding material box 8; then it is reset.

[0086] When K1=G1, the i-th digit I1=K1-n+1;

[0087] When K1=G2, the i-th digit I1=K1-n+2;

[0088] When K1=G3, the i-th i=K1-n+3;

[0089] When K1=G n At that time, I1 = K1;

[0090] The discharge conveyor belt 6 continues to move forward (K2-K1)L stops, the I2th push-pull discharge electromagnet 7 is activated, pushing the steel substrate next to the I2th push-pull discharge electromagnet 7 into the corresponding material box 8; then it resets.

[0091] When K2=G1, the i2th term is K2-n+1;

[0092] When K2 = G2, the i-th digit I2 = K2 - n + 2;

[0093] When K2=G3, the i2th term is K2-n+3;

[0094] When K2=G n At that time, the second i = K2;

[0095] The discharge conveyor belt 6 continues to move forward (K3-K2)L stops, the 13th push-pull discharge electromagnet 7 is activated, pushing the steel substrate next to the 13th push-pull discharge electromagnet 7 into the corresponding material box 8; then it resets.

[0096] When K3 = G1, the I3th digit = K3 - n + 1;

[0097] When K3 = G2, the I3th digit = K3 - n + 2;

[0098] When K3 = G3, the i3th term = K3 - n + 3;

[0099] When K3=G n At that time, I3 = K3;

[0100] The discharge conveyor belt 6 continues to move forward (K) n -K n-1 L stops, number I n The push-pull discharge electromagnet 7 will stop at the I...n The steel base next to the push-pull discharge electromagnet 7 is pushed into the corresponding material box 8; then it is reset.

[0101] When K n When =G1, the I-th n =K n -n+1;

[0102] When K n When =G2, the I-th n =K n -n+2;

[0103] When K n =G3, the Ith n =K n -n+3;

[0104] When K n =G n At that time, the I n =K n .

[0105] If K1, K2, K3, ..., K n If multiple adjacent numbers are the same, then multiple push-pull discharge electromagnets 7 will act simultaneously to push multiple steel substrates on the discharge conveyor belt 6 into multiple corresponding material boxes 8.

[0106] Example 1

[0107] Taking the above example with n=4, m=6, W0=1.5g, a=0.02g: the weights of the four steel substrates are simultaneously measured to be 1.54g / 1.52g / 1.49g / 1.58g, and then the assigned values ​​G1=6 / G2=4 / G3=2 / G4=5 are obtained:

[0108] The four weight data points 6, 4, 2, 5 obtained from the electronic scale 4 are sorted in ascending order, resulting in the order 2, 4, 5, 6.

[0109] The discharge conveyor belt 6 moves forward 2L and stops. Since G3=2, the first (=2-4+3) push-pull discharge electromagnet 7 is activated, pushing the steel substrate weighing 1.49g into the corresponding material box 8 (W≤1.5 gear), and then resets.

[0110] The discharge conveyor belt 6 continues forward for 2 (=4-2)L and then stops. Since G2=4, the second (=4-4+2) push-pull discharge electromagnet 7 is activated, pushing the steel substrate weighing 1.52g into the corresponding hopper 8 (1.5). <W≤1.52 gear), then reset;

[0111] The discharge conveyor belt 6 continues to move forward 1 (=5-4)L and stops. Since G4=5, the 5th push-pull discharge electromagnet 7 starts, pushing the steel substrate weighing 1.58g into the corresponding material box 8 (1.56<W≤1.58 gear), and then resets.

[0112] The discharge conveyor belt 6 continues to move forward for 1 (=6-5)L and then stops. Since G1=6, the 3rd (=6-4+1) push-pull discharge electromagnet 7 is activated, pushing the steel substrate weighing 1.54g into the corresponding material box 8 (1.52<W≤1.54 gear), and then resets.

[0113] Example 2

[0114] Taking the above example with n=4, m=6, W0=1.5g, a=0.02g: the weights of the four steel substrates are simultaneously measured to be 1.52g / 1.54g / 1.46g / 1.52g, and then the assigned values ​​G1=5 / G2=5 / G3=5 / G4=2 are obtained:

[0115] The four weight data points taken by the electronic scale 4 are assigned the values ​​5, 5, 5, 2 and sorted in ascending order, resulting in the order 2, 5, 5, 5.

[0116] The discharge conveyor belt 6 moves forward 2L and stops. Because G4=2, the second push-pull discharge electromagnet 7 starts, pushing the steel substrate weighing 1.52g into the corresponding hopper 8 (1.5g). <W≤1.52 gear), then reset;

[0117] The discharge conveyor belt 6 continues forward for 3 (=5-2)L and then stops. Since G1=G2=G3=5, the 2nd (=5-4+1)th push-pull discharge electromagnet 7, the 3rd (=5-4+2)th push-pull discharge electromagnet 7, and the 4th (=5-4+3)th push-pull discharge electromagnet 7 are simultaneously activated, pushing the steel substrate weighing 1.52g into the corresponding material box 8 (1.5g). <W≤1.52), push the steel substrate weighing 1.54g into the corresponding hopper 8 (1.52 <W≤1.54), push the steel substrate weighing 1.56g into the corresponding hopper 8 (1.54). <W≤1.56 gear), then reset.

[0118] At this point, one weighing cycle ends, and we return to step (1).
